Have a new Sio/Scan weather station model 81690, that does not have the correct pressure, I don,t know how to set it to my area. Would appreciate any help.

The way to calibrate barometric pressure is to compensate for elevation. You can find your elevation at Google Eath, or at this site by typing in the name of your town, and zooming in on your location:

After finding your elevation, you need to subtract the loss in pressure due to elevation. Here’s any easy way to calculate the adjustment (this is a close approximation):
Correction = 3.6 millibars x (elevation in feet) / 100.
